Agricultural Drought Pattern in West Java Using Thermal Vegetation Index From Modis-Terra Satellite

This study examines agricultural drought paddy fields in West Java. The aims of this research are to know the pattern and distribution of paddy field drought in West Java and the correlation between drought and the physical characteristics. The agricultural drought is obtained from TVI (Thermal Vegetation Index) model. TVI is derived from MODIS Terra satellite image, which is the ratio between the LST (Land Surface Temperature) and EVI (Enhanced Vegetation Index). Physical factors studied are rainfall, l slope, geomorphology, soil drainage, and irrigation areas. The most severe drought occurred in September 2006 because of El Nino, covering 806,564 ha, and distributed in almost all West Java Province while the lowest occurred in September 2010 because of La Nina, covering 101,959 ha, and mostly distributed in Subang and Indramayu district. Spatial distribution of drought in 2000-2011 has the same pattern. At the start of the dry season (May) drought occurred in the north (along the coast) then expanded to the east / south in the middle of the dry season (July-August) and then increased further to the west at the end of the dry season (September). Incidence of drought has correlation with the physical condition of the area, but the most influential is the rainfall based on Chi-square test

Qualitative and quantitative analysis of perceived liveability in the context of socio-ecohydrology: evidence from the urban and peri-urban Cirebon-Indonesia

In this study, we examine key liveability aspects, viz., ecosystem services (ES), urban services (US), peri-urban services (PS) and human services (HS). Further, disparity in the liveability of urban and peri-urban areas that could hamper sustainability was investigated. The Cirebon Metropolitan Region in Indonesia frequently experiences water security issues. The perceived liveability of this region was assessed using survey data collected in 65 villages within 25 sub-districts. The study demonstrates that ES, US, PS and HS in the analytical framework of importance–performance analysis (IPA) can identify the main areas needing intervention to improve urban and peri-urban socio-ecohydrological systems and liveability. The method of combining qualitative and quantitative IPA schemes developed in this study is novel and is able to support a demand-based approach and comprehensive understanding of place-based needs for long-term liveability in a developing country situation.</p
